This one is new to me. I just had a customer laptop that Chrome had random pop-ups. I ran all of the typical scans, cleanups, reset browsers, etc.... After finishing I opened Chrome and navigated to my support webpage to test. ** Again it has pop-ups** I opened Chrome Extensions and found "Random Ad Generator" Have you guys come across this? Why didn't ADW or any of the other cleanup utils not spot this thing?

Not being a dick with this reply, but it's gonna depend how you read it.... I would say because nothing's perfect, your question would be better suited to the developers of the programs you ran. It sounds like you did the right thing though, testing Chrome to check it and removing the extension manually. I've had to do this myself on a few occasions, than all of a sudden I notice one of the programmes does start to delete it. So I'd have to assume the Ad generator is just a new one not picked up yet. These plug-ins and extensions seem to come out every other day!? If you don't already, Ccleaner tools section lists all of the add-ons for the most popular browser's as well as startup items, etc.
